A SURFACE RIDGE FROM THE SOUTH WILL SLIDE NORTHWARD TOWARD THE
SAMOAN ISLANDS ON TUESDAY NIGHT INTO WEDNESDAY. FAVORABLE WEATHER
CONDITIONS ARE EXPECTED DURING THE NEXT COUPLE OF DAYS WHILE STRONG
SOUTHWEST WINDS ALOFT COERCE HIGH CLOUDS TO DRIFT FARTHER NORTH-
NORTHEAST OF THE REGION. AS THE SURFACE TROUGH APPROACHES THE FCST
ZONES FROM THE SOUTH...DRY WEATHER CONDITIONS ARE EXPECTED THUS COOLER
